I'm looking for the clearance and creepage requirements between live voltage (230V) and SELV (Safety Extra Low Voltage) in the EU.
I had a look at this and other questions, but I rarely see numbers mentioned, and when I do see them, they often contradict each other. So far I've seen clearance distances of 3mm, 5.5mm and 6mm. For creepage I haven't any numbers at all.
So, what is required?
(PS: can somebody add the selv tag? Thanks)
